Ghost Online

Ghost Online was a 2D sidescrolling fantasy MMORPG from Korean company MGame. The game was also known as Ghost Soul, from its system that let players absorb the souls of monsters they defeated. Ghost Online had traditional quests and hunting for character advancement, and limited customization.

The game's story concerned a demon hunter who used forbidden powers and was corrupted in the process. An attempt to cleanse his own soul ended up with him being reincarnated as the player character. All characters began as peasants and could work their way up into one of five class paths -- Warrior, Assassin, Goliath, Treasure Hunter, or Magician/Taoist. Monsters in the game came in several types based upon method of attack and manner of movement (such as flying), but all of the bosses were hybrid animal/humans with designs inspired by the twelve animals of the Chinese zodiac.

Ghost Online was free to play and item shop supported. Its US version was cancelled in 2009, and the global version soon followed.
